GSC Power-Division Billet Toyota 2JZ-GTE VVTi S2 Camshafts Set
Part # GSC 7031S2
GSC Power-Division billet S2 cams for the VVTI Toyota Supra 2JZ-GTE. The only forged billet core *** VVTi Camshafts on the market. The S2 profile is designed for those running a large single turbo, turbos larger than 71mm typically. These cams will not have bottom end losses over our S1 cams on larger frame turbos. Gains of 60-100 WHP (depending on turbo) have been seen by simply bolting the S2 cams in and reshimming. These cams require upgraded valve springs.
- Designed for a rev range of 4000-8500 RPMs
- 800WHP-1500 WHP camshaft set
- Rougher than stock idle
Install Note:
It is necessary to inspect the S2 profile in your VVTi cylinder head for casting clearance prior to running. With the higher lift and the OEM castings, some need to be clearanced to allow for the cam to spin freely in the head without contact. Please maintain 0.02″ (0.5mm) clearance from the cylinder head casting.
We recommend the conical spring kit for VVTi cylinder heads due to clearance issues with the beehive spring on some castings.
